The Pseudomonas stutzeri strain A1501 (formerly known as Alcaligenes faecalis) fixes nitrogen under microaerobic conditions in the free-living state and colonizes rice endophytically. The authors characterized a region in strain A1501, corresponding to most of the nif genes and the rnf genes, involved in electron transport to nitrogenase in Rhodobacter capsulatus. The region contained three gro...

In order to evaluation the effects of soil organic matter and biofertilizer on chickpea quality and biological nitrogen fixation, field experiments were carried out in 2007 and 2008 growing seasons. In this research the effects of different strategies for soil fertilization were investigated on grain yield and yield component, minerals, organic compounds and cooking time of chickpea. Experiment...

this study was conducted in acompletely randomized block design with three replications using three concentrations of 107, 105, and 103cfu/ml of azotobacter isolated from the rhizosphere of karun varieties of barley (az. salentris) and standard az.chrococom along with control (zero concentration of bacteria). the aim of this study was to study the reactions of barley plantin response to inocula...

considering the importance of medicinal plants growth and biological application of fertilizers with sustainable agricultural production in order to eliminate or reduce chemical input to achieve desirable and sustainable quality, an experimental research was  conducted based on a randomized complete block design with two factors of chemical nitrogen (46% urea nitrogen) at  two levels (zero, 25 ...

A field experiment was conducted at the experimental site of Department Soil Science and Water Management, College Horticulture Forestry, Neri, Hamirpur (Himachal Pradesh). The consisted eleven treatments which were carried out in randomized block design with three replications. Observations for micronutrient uptake soil physical properties recorded it found that lowest bulk density achieved tr...
